Comparative analysis and trends in liver transplant hospitalizations with Clostridium difficile infections: A 10-year national cross-sectional study.

GOALS AND BACKGROUND: Clostridium difficile infection (CDI) is the leading cause of antibiotic-associated diarrhea in the United States. We aimed to determine comparative trends in inpatient outcomes of liver transplant (LT) patients based on CDI during hospitalizations. METHODS: The national inpatient sample database was used to conduct the present retrospective study regarding CDI among the LT hospitalizations from 2009 to 2019. Primary outcomes included 10-year comparative trends of the length of stay (LOS) and mean inpatient charges (MIC). Secondary outcomes included comparative mortality and LT rejection trends. RESULTS: There was a 14.05% decrease in CDI in LT hospitalizations over the study period (p = .05). The trend in LOS did not significantly vary (p = .9). MIC increased significantly over the last decade in LT hospitalizations with CDI (p < .001). LT hospitalizations of autoimmune etiology compared against non-autoimmune did not increase association with CDI, adjusted odds ratio (aOR) 0.97 (95% confidence interval [CI] 0.75-1.26, p = .87). CDI was associated with increased mortality in LT hospitalizations, aOR 1.84 (95% CI 1.52-2.24, p < .001). In-hospital mortality for LT hospitalizations with CDI decreased by 7.75% over the study period (p = .3). CDI increased transplant rejections, aOR 1.3 (95% CI 1.08-1.65, p < .001). There was a declining trend in transplant rejection for LT hospitalization with CDI from 5% to 3% over the study period (p = .0048). CONCLUSION: CDI prevalence does not increase based on autoimmune LT etiology. It increases mortality in LT hospitalizations; however, trend for mortality and transplant rejections has been declining over the last decade.

Impact of Drain Placement and Duration on Outcomes After Pancreaticoduodenectomy: A National Surgical Quality Improvement Program Analysis.

BACKGROUND: The decisions to routinely place a drain after pancreaticoduodenectomy and how long to leave the drain remain controversial due to conflicting evidence and significant variations in clinical practice. This study aims to address those questions by using a large national database and a rigorous analytical model. METHODS: The American College of Surgeons National Surgical Quality Improvement Program 2015-2016 Pancreatectomy Participant Use Data Files were used to identify patients who had undergone pancreaticoduodenectomy (n = 7583). Univariable and multivariable binomial regression analyses were performed to control for potential confounders and various preoperative risk factors. Cox regression with drain as a time-dependent covariate, conditional on having a drain placed, was used to examine the association between the drain remaining in place and morbidities. RESULTS: Of 7583 patients, drains were placed in 6666 (87.9%). Drain placement decreased the risk of developing serious morbidity (relative risk [RR] 0.73, 95% confidence interval [CI] 0.65-0.82), overall morbidity (RR 0.79, 95% CI 0.72-0.87), and organ space surgical site infection (RR 0.72, 95% CI 0.61-0.85). Drain placement did not change the risk of developing a clinically relevant postoperative pancreatic fistula (RR 0.96, 95% CI 0.78-1.19). However, for those with drains placed, length of drainage was independently associated with serious morbidity (hazard ratio [HR] 3.06, 95% CI 2.65-3.53), overall morbidity (HR 2.48, 95% CI 2.20-2.80), and organ space surgical site infection (HR 1.47, 95% CI 1.23-1.74). CONCLUSIONS: Routine drain placement following pancreaticoduodenectomy may decrease postoperative complications, including serious morbidity, overall morbidity, and organ space surgical site infections; however, length of drainage was associated with increased risk of the previously-named complications. These results support the routine placement and early removal of intraoperative surgical drains in pancreaticoduodenectomy.

From random to precise: updated colon cancer screening and surveillance for inflammatory bowel disease.

Patients with inflammatory bowel disease (IBD) are at increased risk of developing colorectal cancer (CRC). The pathogenesis of CRC in IBD differs from sporadic cancer, with the burden of inflammation being an important contributing factor. Other risk factors for developing CRC in patients with Crohn's disease (CD) or ulcerative colitis (UC) includes a family history of CRC, personal history of dysplasia, history of strictures, or primary sclerosing cholangitis (PSC). Dysplasia is the precursor of cancer and ensuring effective surveillance strategies is vital for early detection and intervention. In the past, dysplasia detection relied on random biopsies, but recent studies have shown that, with the adaptation of high-definition white light endoscopy (HD-WLE), dye sprayed chromoendoscopy (DCE) and virtual chromoendoscopy (VCE), dysplasia detection has improved. While there exists a certain degree of consensus amongst experts regarding the management of dysplasia, it is important to implement a personalized approach to each patient's care. Our review focuses on advancements in the past two decades, specifically highlighting the modifications that have been implemented since the SCENIC guidelines. It also explores future directions, including the potential implementation of stool studies as a non-invasive tool for surveillance and the emerging role of artificial intelligence (AI) in dysplasia detection.

Substance abuse and inpatient outcomes in inflammatory bowel disease hospitalizations in the United States: a propensity matched analysis.

Background: Inflammatory bowel disease (IBD) is a chronic intestinal inflammation resulting in a genetically susceptible population. The present study aimed to look at the effect of substance abuse on IBD hospitalizations in the United States. Methods: We identified primary IBD hospitalizations with substance abuse using the National Inpatient Sample database (2016-2019). A matched comparison cohort of IBD hospitalizations without substance abuse was identified by 1:N propensity score matching using the nearest-neighbor method, based on demographics, hospital-level factors, and comorbidities. Results: We matched 4437 IBD hospitalizations with a diagnosis of substance abuse to 4528 hospitalizations without abuse. The median age was higher in the substance abuse group than no abuse (44 vs. 38 years, P<0.001). There was a higher prevalence of discharge to care facilities (2.9% vs. 2.2%) and against medical advice (4.9% vs. 1.8%) in the substance abuse group compared to the no abuse (P<0.001). The median length of hospital stays (LOS) (P=0.74) and hospitalization charge did not differ significantly (P=0.57). There was no significant difference in 30-day inpatient mortality among cohorts (adjusted hazard ratio 0.74, 95% confidence interval 0.32-1.81; P=0.54). There was a higher prevalence of psychoses (2.5% vs. 1.3%) and depression (18.8% vs. 15.7%) in IBD hospitalizations with substance abuse compared to those without abuse (P<0.001). Conclusions: This study reports no difference in median LOS, hospitalization charge, or mortality risk in IBD hospitalizations based on substance abuse. There is a higher prevalence of psychoses and depression in IBD patients, requiring screening for substance abuse to improve overall outcomes.

Association of nonalcoholic fatty liver disease with acute cholangitis: a nationwide propensity-matched analysis from the United States.

Background: Nonalcoholic fatty liver disease (NAFLD) has previously been linked to several disease states with an impact on patient outcomes. However, clinical evidence on the association between NAFLD and acute cholangitis (AC) remains scarce. We aimed to evaluate the potential association between NAFLD and AC. Methods: We conducted a retrospective cohort study using the US National Inpatient Sample database from 2016 to 2019 to analyze primary AC hospitalizations with NAFLD compared to non-NAFLD in a 1:1 propensity-matched population. Results: A total of 1550 AC patients with NAFLD were matched to 1550 AC patients without NAFLD. NAFLD had a higher association with AC when compared to patients without NAFLD, with an odds ratio of 2.33 (95% CI [1.81-3.0], P < 0.001). The length of stay was higher in NAFLD than in non-NAFLD (4 vs 3 days, P < 0.001). The median inpatient charges in NAFLD were also higher than in the non-NAFLD cohort ($36,182 vs $35,244, P < 0.001). Inpatient mortality was higher in NAFLD compared to non-NAFLD (1.6% vs 0%, P < 0.001). There was an increased prevalence of portal vein thrombosis (3.2% vs 0%), acute kidney injury (24.2% vs 17.7%), sepsis (3.2% vs 1.6%), mechanical ventilation (3.2% vs 0%), and percutaneous cholecystostomy tube insertion (3.2% vs 1.6%) in NAFLD compared to non-NAFLD (P < 0.05). NAFLD also had a higher association with acute cholecystitis, with an odds ratio of 3.70 (95% CI [3.19-4.29], P < 0.001). Conclusions: This study showed an association between NALFD and AC, resulting in increased length of stay, hospital charges, and inpatient mortality. Underlying NAFLD also increases acute complications of AC.

Trends in hospital admissions and mortality among inflammatory bowel disease patients with substance use disorder: a 10-year United States nationwide analysis.

Background: Patients with inflammatory bowel disease (IBD) and substance use disorder (SUD) may have worse clinical outcomes. However, data specific to the hospital admission and mortality rates among IBD patients with SUD are scarce. Our objective was to assess trends in admission, healthcare expenses, and mortality for IBD patients with SUD. Methods: We conducted a retrospective study using the National Inpatient Sample database to analyze SUD (alcohol, opioids, cocaine, and cannabis) among IBD hospitalizations from 2009 to 2019. Results: A total of 132,894 hospitalizations for IBD had a secondary diagnosis of SUD. Of these patients, 75,172 (57%) were men and 57,696 (43%) were women. The IBD-SUD cohort had a longer length of stay than the non-SUD cohort (P < 0.001). The mean inpatient charges for IBD hospitalizations with SUD increased from $48,699 ± $1374 in 2009 to $62,672 ± $1528 in 2019 (P < 0.001). We found a 159.5% increase in IBD hospitalizations with SUD. The hospitalization rate increased from 3492 per 100,000 IBD hospitalizations in 2009 to 9063 per 100,000 in 2019 (P < 0.001). In-hospital mortality for IBD hospitalizations with SUD increased by 129.6% (from 250 deaths per 100,000 IBD hospitalizations in 2009 to 574 deaths per 100,000 IBD hospitalizations in 2019) (P < 0.001). Conclusions: Over the last decade, there has been a rise in IBD hospitalizations with SUD. This has resulted in a longer length of stay, higher inpatient charges, and higher mortality rates. Identifying IBD patients potentially at risk for SUD by screening for anxiety, depression, pain, or other factors has become crucial.

Considerations for an Alternative Site of Islet Cell Transplantation.

Islet cell transplantation has been limited most by poor graft survival. Optimizing the site of transplantation could improve clinical outcomes by minimizing required donor cells, increasing graft integration, and simplifying the transplantation and monitoring process. In this article, we review the history and significant human and animal data for clinically relevant sites, including the liver, spleen, and kidney subcapsule, and identify promising new sites for further research. While the liver was the first studied site and has been used the most in clinical practice, the majority of transplanted islets become necrotic. We review the potential causes for graft death, including the instant blood-mediated inflammatory reaction, exposure to immunosuppressive agents, and low oxygen tension. Significant research exists on alternative sites for islet cell transplantation, suggesting a promising future for patients undergoing pancreatectomy.
